The final of My Genius Idea has arrived, CBBC's search for brand new inventing talent.
We started out with 18 great ideas and we're now down to the last two inventors, but which one of them will win the competition? They have to convince judge, and expert inventor, Tom Lawton that they have the genius idea. Will he choose the bike safety system, or the device to protect marine life? It's all to play for as Johny Pitts presents the finale to the series.
